2009 Mini Stock Tire Rules & Procedures
2/27/09
The only tires approved for the 2009 season:
Goodyear D2832 L22 x 8.0 x 13 $102.50 each
D2833 R23 x 8.0 x 13 $102.50 each
The official tire supplier is Concept Race Cars & Graphics (360) 805-5169. Purchaser must declare which driver the tires are for at the time of purchase. A list with the serial numbers of all tires sold, and for which driver will be kept. This list includes practice tires. List will be turned over to the tire officials every week at the track. Any tires purchased may be taken home.
Driver’s who participate in the season opener on April 11th, 2009 will be allowed to stamp in up to 6 tires that night as “race tiresâ€. Any combination of new or used tires is allowed to make up these six tires; however it is highly recommended that new tires are used. This will maximize the use of the tires as averaged throughout the season. All six tires whether new or used, must have been purchased from Concept in 2009 and meet all established rules.
Driver’s competing for the first time after April 11th, will be allowed to stamp in, 4 tires for that night of racing. Any combination of new or used tires is allowed to make up these four tires; however it is highly recommended that new tires are used. This will maximize the use of the tires as averaged throughout the season. All four tires whether new or used, must have been purchased from Concept and meet all established rules. After April 11th, any driver competing for the first time must start in the back of the pack, in the heat race and the main event that night. This is regardless of the combination of new/used tires used to make up the allowed four tires.
There is no limit on number of practice tires that can be purchased in a season. At any time tire supply versus demand warrants such, a purchasing limit of 6 tires, per driver, per week may be imposed, assuring the greatest selection for all competitors at all times. This helps to eliminate drivers from stockpiling large quantities of commonly desired tire sizes. It is up to the sole discretion of Concept as to if and when this may happen. It is our intent to provide all drivers equal opportunity in choice of tires at all time. Stagger numbers available will vary throughout the season. This is common, and in no way can it be manipulated as Goodyear provides a “range†of sizes, and cannot guarantee any quantity of any size. It is up to the driver to be sure he/she maintains adequate contact with tire supplier in order to have best choice at tire sizes. Drivers purchasing tires at the track on race day will justifiably have a smaller cross section of stagger choice, as the other drivers have purchased ahead of them.
Each week the driver will be responsible for ensuring that all new tire(s) are presented to the Tire Officials at least 30 minutes prior to qualifying (heat races, or time-ins). It is the responsibility of the driver to be sure that all tires are stamped/marked on both sides. If a stamp/mark is “rubbed†off in competition or cannot be clearly read, it is the sole responsibility of the driver to bring the tire to tire officials for replacement stamp/mark. Tires will be checked and recorded by the Tire Officials when the cars are scaled just prior to the main event.
All serial numbers, bar code tags, and/or identification numbers of tires must remain unaltered. Any tire not having any one of these stamps/marks, serial numbers, bar codes, and/or ID numbers, and cannot otherwise be identified as being the proper tire for the evening will be considered illegal and will be confiscated. The penalty for illegal tires will be the loss of all points for the day, a $250.00 fine and the driver will lose the right to stamp in a new or used tire on their next eligible night to stamp in a tire. ALL illegal tires will be confiscated. No tire softener will be allowed. Tires must durometer within 3 points of factory specifications. The tire officials will be allowed to check all Race tires brought into the Speedway. Any tire deemed illegal by the tire officials will be confiscated.
Any tires found on wrong car number will be grounds for disqualification as well as being subject to fines, suspension and/or loss of points. Tires will also be confiscated. Tires may not be transferred between drivers for any reason. Once a driver checks a tire in, it is for them to use only. No one else. Multiple drivers using same car will be given an alternate brand on the tire, allowing them to use the same tires.
Drivers wishing to replace a tire that has been damaged or destroyed must present said tire to tire officials no later than 30 minutes following the conclusion of the race in which tire was damaged. Only tires considered “new†for the night are considered eligible for replacement. A tire is considered new if it has no more than a total of 20 green flag laps of competition on it since being checked in as that night’s allowable tire. The 20 lap limit includes heat race and main event laps. Practice and caution laps are not considered. Eligibility of a tire for replacement is subject to the final decision of tech officials. If a tire is deemed eligible for replacement, officials will determine an average tread depth using multiple readings in various places on tire. Replacement tire will have at a maximum of the same amount of tread on damaged tire as determined by this measurement. Replacement tire must have this depth or less remaining to be accepted. Tire used for replacement must have been purchased from Concept in 2009. It can come from your practice inventory and have been purchased at any time including that day. Final approval is subject to decision of official.
Driver’s will be allowed to stamp in ONE new tire every other race they participate in. (participate means, competed in the main event). Scuffed or used tires will not be stamped unless they are to be treated as your new tire for that race night. If you have a used tire stamped in, you give up the right to stamp in a new tire that night. You must run the tire you stamped in that night. There will be no “stockpiling†of tires. If you choose not to check in a tire on the night it is available to you (per every other race competed in rule) that option is again available the next race you participate in.
You must run the tires you qualify on in the main event. When time-ins are used for qualifying, the tires you ran for time-ins must be run in the heat race, and the main event. When heat races are used for qualifying, the tires you ran in the heat race must be run in the main event.
New tires must be run a minimum of 20 laps of green flag racing (including heat race and main event), or they will still be considered new tires for the next night of racing.
Wheels cannot exceed 8†in width. All wheels must be heavy duty or reinforced steel (i.e. Basset, Aero, etc.) with a maximum backspace of 3†as measured on the backside of the wheel. No spacers will be allowed.
If not specified that you can do it, you probably can’t. Check with the Tire Official and be safe. All rules subject to Tire Official interpretations.
